Abstract (en)

[origin: EP3903924A1] A fluid treatment device with a new configuration is provided. The fluid treatment device F is provided with an upstream treatment unit defined by treatment surfaces 1, 2 that rotate relative to each other, and a downstream treatment unit arranged downstream of the upstream treatment unit. The upstream treatment unit is configured such that, by passing the fluid to be treated into an upstream treatment space 3 defined by the treatment surfaces 1, 2, the fluid to be treated is subjected to upstream treatment. The downstream treatment unit is provided with a downstream treatment space 81 which performs the function of retaining and mixing the fluid to be treated by means of a labyrinth seal. An upstream outlet 4 of the fluid to be treated from the upstream treatment unit opens into the downstream treatment space 81, and the downstream treatment space 81 is configured to use the labyrinth seal to perform the function of controlling retention time. The downstream treatment space 81 is provided with narrow seal spaces 84, and retention spaces 83 arranged upstream of the seal spaces 84 and wider than the seal spaces 84, and the upstream outlet 4 opens to a retention space 83.
